' UNITED STATES CHARLES 0. BROWNELL, OF BATTLE CREEK, MICHIGAN, SSIGNCRTC BATTLE CBE BREAD WBAPPINGMACHINE C0., 0F OF MICHIGAN.

BATTLE CREEK, MICHIGAN, A CORPORATION WRAIPING MACHINE.

Application led January 3, 1921.l Serial No. 434,675.:

To all lwhom. it may concern.'

Be it known that I, CHARLES. O. BROWN- ELL, a citizen of the UnitedStates, residing at Battle Creek, county of Calhoun, State of Michigan,have invented certain new and useful Improvements in` Wrapping Machines,of which the following is a specification.

This invention relates to improvements in wra ping machines.

y improvements are especially designed by me and I have illustrated thesame as embodied in machines for wrapping bread. My improvements are,however, capable of embodiment and various features are desirable whenembodied in machines for wrappirg other articles. he main objects ofthis invention are: First, to provide an improved wrapping machine whichis quite compact and at the same time of large capacity.

Second, to provide in a wrappingmachine an improved means for carryingthe articles into the machine and through the wrapping mechanism anddelivering the wrapped ar- .ticles- '.lhird, to provide an improvedwrapping machine which is well adapted for the handling of comparativelydelicate objects such as loaves of bread.

Further objects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodi- .ment of' my invention isclearly illustrated in the accompanying drawing forming a part of thisspecification, in which:

In the drawingsimilar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring` to the drawingv the frame of the vmachine is preferablyformed of two main parts 1 and 2, each consisting of side and crossmembers arranged to provide rigid supports for various shafts, ways andmovable parts. The two frame members are detachably connected by meansof the bolts 3 arranged through slots 4 in the overlapping arms 5. Thedetails of the frame form no part of this invention and they aretherefore not further described herein.

The frame member 2 is preferably provided with panels 6. I preferablydrive my machine by means of an electric motor shown conventionally at7, the motor being mounted in the lower part of the frame. The loaves ofbreadB or other articles to be wrapped are introduced and alsodischarged from the front end of the machine. The articles are convtyedto the machine by the supply conveyor esignated generally by the numeral9 from which they are shifted to the feed conveyor designated generallyby the numeral 10 by the shifter designated generally by the numeral 11.

The articles are delivered by the feed conveyor 10 to the elevatingconveyor by which they are delivered to the wrapping and sealingconveyor designated generally by the numeral 13. The conveyor 9 consistsof a frame .14 supported at its front end by the standard 15 and at itsrear end by the ,bracket 16 on the main frame of the machine.

The articles 8 are placed upon the conveyor belts 17 by an operator 0ras may be desired, by belts traveling between the side bars 18 so thatthe articles are carried along by the belts and delivered thereby ontothe shifter way or table 20. A' stop bar 21 is disposed opposite to thebelts 17 so that the articles are delivered against the same.

The table or way 20 has a slot 22 throu h which the flights 23 projectto engage t e articles and push them along the table 20 onto the slideway 24 of the feed conveyor 10.

The flights 23'are mounted .on sprocket chain 25 supported by sprocketson the shafts 26 and 27see Fig. VII.

The shaft 27 is connected by the pinions 28 to the shaft 29 havingpulleys 30 thereon for the belts 17 so that these belts are driventhrough the conveyor chain 25. The feed conveyor 10 is provided withsprocket chains 31 disposed at the sides of the way 24 and carryingflights 32 which travel on their forward reach above the way and pushthe articles along thereon. Side bars 33 and 34 are provided to guidethe articles as they are carried along by the flights.

The articles 8 are delivered by the conveyor 10 against'the stop bars 35in which position they are engaged by the arm-like flights 36 of theelevating conveyor 12. These flights 36 are mounted on rods or rockshafts 37 carried by the conveyor chains 38 on the sprocket wheels 39and 40-see Fi IX. These rock shafts are provided wit rollers 41traveling in cam ways 42, the rock shafts being also provided with arms43 having rollers 44 traveling in these cam ways, the cam ways beingarranged so that the flights 36 are supported in an upright position ontheir ascending movement, engaging the articles as they are supported bythe bars 45 t0 which they are delivered by the feed conveyor carryingthem upward between the bars 35 and the guide plate 46- see Fig. IX. Thefeed conveyor carries the articles to the position shown in Fig. X inwhich position the articles engages a sheet of wrapping paper 47 and thewrapper receives its inltial wrappin The articles are then engaged bythe iii its 48 of the sealing conveyor and carrie upon the slide way I49 of the sealing conveyor.

The wrapping sheets 47 are carried across the path of the articles asthey areelevated by the elevating'conveyor, one edge of the sheets beingthe other y the paper feed ta le 51, the articles engaging the sheetsfrom their undersides. The sheets are wrapped across the top and aboutthe sides thereof as they are elevated and carried between the wrappingmembers 52 and 53 which wrap the paper over the top and sides as shownin Fig. IX.

As the articles reaches the elevated position shown in Fig. X, it isengaged by the wrapper holder 54 yieldably supported by the arm 55 andthe links 56 and 57. When the article reaches this position, it isengaged by the rear bottom folder 58 which folds the bottom flap 59under the article as' shown in Fig. X. This folder is also rovided withrear end flap folders 60 w ich fold the rear end fiaps forwardl A frontbottom flap folder 61 1s arranged to engage the front bottom Hap 62 andfold it rearwardly over the rear bottom flap 59 as shown in Fig. X. Asthe article is engaged by the ap folders, the flight 36'drops awayleaving the article supported by the folders until it is carried on tothe slide ways 49 of the wrapping and sealing con- Iveyor.

supported by the fin ers 50 and lll) :Maese wheels for the elevatingconve or chains are mounted-.see Figs. I and I vThe lia folder 61 1sactuated by the pinion 72 an the rack 73. The rack 73 is actuated by thelever 74 pivoted at 75 and actuatedby a cam 76 on the shaft 77 connectedby the sprocket chain 78 and suitable sprockets to the shaft 79 which isconnected by the train -of gears 80 to the main drive 81 connected b thebelts 82 to the motor 7--see Figs. I X, and XII.

As the folder 61 completes its operation, the article is engaged by oneof the flights 48 of the Wrapping and sealing conveyor 13.

- The sprocket chains 83 carrying these flights are mounted on sprockets84 carried by shafts 85 and 85 on the pedestals 86 so that the sprocketchains are supported above the way 49 and the flights swing over thearticle in lts initial wrapping position asv shown in Fig. X, pushin italong on the way 49 between the Hap ilders and side plates. The fiightsare provided with arms 88, the arms and flights havin rollers 89traveling between guides 90 w ile the flights are on the lower reach oftheir travel so that they are supported in a vertical position.

As the articles are carried along by the flights 48, the forward endfiaps are engaged by the stationary flap folders 91 positloned at thesides of the conveyor. folders are supported by arms 92. The bottom enddaps are then engaged by the bottom flap folders 87 which turn the sameupwardly against the folded forward and rear end flaps 93 and 94. Thetop end flaps are then engaged by the rotary flap folders 95 and foldeddown upon the folded bottom flaps, the several steps being illustratedin Fig. XI, (A) indicating the position of the flaps after passing thefolder 91, and (B) after passing the folder 93.

The rotary flap folders 95 are driven by the sprocket chain 96 andsuitable sprockets from theshaft 77-see Fig. XH. As the wrapped articlesare further advanced they come into contact with the sealing plates 98and are then carried between the cooling plates 99 and discharged ontothe chute 100.

To hold the article to the way and prevent creeping of the wrapperthereon as it is acted upon by the folders, I provide a floating bar 101which is supported by the links 102 above the way 49 so as to engage thetops of the wrapper.

I will now describe in detail the means by which the flights of theelevating conveyor are controlled so that they drop away or fall awayfrom the article when it has reached its initial Wrapping position asshown in Fig. X and so that the flights do not interfere with theoperation of the bottom folders which as stated not only serve thepurpose of folders but also support the article until it is moved alongon the way 49.

tinued movement of von the rock sha t These flap The de ways 42 for therollers 44 of the lli ts have vertical side portions and curve endportions as shown in Fig. 1X. At the upper end of the guide way 42 is aswitch way 103 controlled by the switch 104 pivoted at 105. As the4flights, travel u wardl Y to the position shown in Figs. li A and 1 therollers on the rock shafts 37 engage the switch 104 swinging itacrossthe way 42 so that the roller on the arm 43 is gulded by the switch 104into the switch way 103. This tilts the flight rock shaft dropping theflight downwardly and away from the article as shown in F1 X. The contheHight tilts it still further as shown by dotted lines in Fig. IXA sothat it passes from below the article.

As the flight supporting rock shaft iscarred over the u per sprocket 39,the roller and arm pass into the way enlargement 106 at the u downwardreach or trave of the flights. The purpose of this way enlargement 106is to permit the ilights to tilt still further and thereby economize inthe space required for the conveyor.

I provide the way with a reversing space 107 adapted to permit theswinging of the arm 43 when the flight engages the stop 108 and isreversed thereby as indicated by dotted lines in Fig. 1X,

To prevent a rebound and the vibrations of the rock shaft in thereversing space, li provide a pivoted guide 109 at the bottom of thereversing space 107 so that the roller on the rock shafts passes infront of this guide while the roller on the yarm may pgss under the sameas indicated in Fig.

With this arrangement of parts, the ights are causedto quickly drop awayfrom the articles when they have reached their wrapping position, andfurther the conveyor is compact, it being one of the main objects of myinvention to provide a structure which is of large capacity and at thesame time quite compact.

Furthering this feature of eompactness, li arrange the pa r feedmechanism between the feed and t e sealing conveyors.

The paper roll 110 is mounted at the front of the machine andv the paperpassed over the guide rolls 111 and 112 between the feed rolls 113 and114, the roll 113 being a driven roll and the roll 114- a pressure roll.At the rear of the lfeed rolls are the cutter bar 115 and coacting shearbar 116. The shear bar is carried by `the arms 117 on the roch shaft118. These parts are shown in Figs. XV, XVI and XVII.

A tensioning device 118 is provided between the roll of paper and thefeed rollerssee Fig. XV.

The details for operating the shear bar and driving the feed rolls arenotA described per end of the- Fig. VII.

as they form no part vof my present invention. I desire to point out,however, that the feeding of the paper is controlled by the articles onthe feed conveyor, a stop 119 on the rock shaft 120 being arranged toproject through aslot 121 in the conveyor way 24 so as to be engaged bythe articles passing along the way.

This rock shaft 120 is connected by the link 122 to an arm 125 on therock shaft 126 which is in turn connected by the link 127 to the arm 128on the control mechanism.

The feed paper mechanism is driven from the shaft 79 having a gearthereon meshin with a gear 130 on the shaft 131. This sha t 131 has agear 132 meshing with a gear 133 on the feed roller which is one of atrain of gears 134 indicated generally by the numeral 134 through whichthe feed roller 113 is driven. The sup ly conveyor described is alsodriven from t is shaft 79, a sprocket chain 135 and suitable sprocketsconnecting the shaft to a beveled gear 136 meshing with a beveled pinion137 on the shaft 26-see The feed conveyor is driven with an intermittentor step by step movement, the driven conveyor shaft 138 being providedwith an intermittent gear 139 meshing with an intermittent gear 140 onthe shaft 141 which has a beveled gear 142 meshing with the beveled gear143 on the shaft 144 which is lconnected by the pinions 145 to the shaft`'T9-see Figs. V and -VIII.

The lower shaft 71 of the elevating conveyor is connected by the beveledgears 146 to the shaft 147 which is connected to the shaft 144 by theuniversal joint 148.

The discharge chute 100 is provided with belts 150, the pulleys for theupper ends of the belts being supported by the shafts 151 driven by thesprocket chain 152 from the shaft 77. A

The driving shaft 85 of the sealing coni veyor is connected to the shaft77 by the sprocket chain 153 and suitable sprockets on the shaft. l

Thus connected, the several mechanisms are properly timed orsynchronized in their operations so-that the machine is entirelyautomatic, the loaves or other articles to be wrapped being delivered tothe supply conveyor 9 from whence they are transferred to the feedconveyor, delivered by the feed conveyor to the elevating conveyor froml which it is carried on to the sealing conveyor, through the sealingmechanism, and delivered to the delivery chute.

My improved wrapping and sealing machine is of large capacity and isquite compact. I have not attempted to illustrate or describe certainmodifications in structural details which I contemplate as I believe thedisclosure made will enable those skilled in the art to which myinvention relates to embod or adapt the same as may be desired.

aving thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
